| | | | | | * instrument Clang's thread sanitizer for tests Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* nDPId-test: Reworked I/O handling to prevent some endless loop scenarios. ↵Toni Uhlig2022-12-02
| | | | | | | | Fixed a race condition in the memory wrapper as well. * nDPId: Instead of sending too long JSON strings, log an error and some parts. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* Improved the point of time when to append the raw packet base64 data to the ↵Toni Uhlig2022-11-15
| | | | | | | | | serializer. * nDPId-test: Increased the max-packets-per-flow-to-send from 3 to 5. This is quite useful for TCP as the first 3 packets are usually part of the three-way-handshake. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* nDPIsrvd: Provide workaround for change user/group.Toni Uhlig2022-11-13
| | | | | | | | * nDPId/nDPIsrvd/c-examples: Parameter parsing needs to be improved if `strdup()` in combination with static strings is used. * Other non-critical fixes. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* nDPId: Fixed base64 encoding issue.Toni Uhlig2022-11-13
| | | | | | | | | | | | * The issue can result in an error message like: `Base64 encoding failed with: Buffer too small.` and also in too big JSON strings generated by nDPId which nDPIsrvd does not like as it's length is greater than `NETWORK_BUFFER_MAX_SIZE`. * nDPId will now obey `NETWORK_BUFFER_MAX_SIZE` while trying to base64 encode raw packet data.
